Question

Can anyone please help me?! I WILL MEDAL!!

Answer 1

hint:
a function, connects one value \(x_0\) to another value \(y_0=f(x_0)\), such that, for a fixed value of \(x_0\) there is \(one\) and only \(one\) value of \(y_0=f(x_0)\)

Answer 2

My best guess on the answer is C. because you can't have 2 of the same domain, right?

Answer 3

That's right!!
for example, if we have these ordered pairs:
\[\Large \left( { - 2,5} \right)\quad \left( { - 2, - 9} \right)\]
we have \(not\) a function, since number \(2\) is connected to the number 5 the first time and to the number 9 the second time, and it is against the definition of a function

Answer 4

Awesome! Thank you!!
